WILLIAM J. P. MOORE. OF NEW YORK. N. Y.

To all l lmm it may warm-n.

Be it known that l. Wnirun J. 1. Monica, a ritizen of the United States. residing at New York. in the eounty of New York and State of New York. have invented eertain new nd useful Improvements in Ball-Bearings, of whit-h the following is a speeitiralimit referent-e being had therein to the areounaurving drawing.

My invention relates to a eonihined hall and roller bearing adapted for use in and with a great variety of niarhines.

()ne of the ohjerts ol the invention is to eoinhine in a single hearing deviee all the advantages possessed separatel) h rollers and balls so that in a thrust hearing the thrust may he ta lt'en ell'ertirelv and equally in all dirertions.

The invention. therefore. eonsists essentialh in a hollow roller or sleeve rontaining witliin the same a spheriral hall. all in rombination with a suitable easingso that the hall may be t't'eelo rotate within the rolling sleeve and the sleeve may he free to re\ol\'e in the easing: and also the invention 1|!- rhldes various details in the eonstrurtion and applieation of the ragesand the asings and other parts for supporting the halls and rollers: and t'nrtln-rluore. it elnhrares nuna-rons details and peenliarities in the eonstrurtion and arrangement of the \::ri olls parts. substantially as will he hereinat' ter deserihed and then more t'nll} pointed out in the rlailns.

In the areonipan ving dtwnring illustrating niv invention: igure l is a transwrse sertion of a hall and roller hearing ronstrltrted in areordanee with Itl present improvements. the same heing partl v in side view.

Fig :2 is a eross-seetion ol the same on the line 2. :3 of Fiji. 1. Fig. I3 is a similar eross seetion of twin or daplirate hearings in one easing. 1

Similar rhararters ol reference designate rot-responding parts throughout the dill'erent lignres of the drawing.

In the t.\'|)lzlfltllltill of my present in ven tion. I have shown the same applied in a easing ronsisting of an outer revolving r ng or evlinder 1 and an inner stattonanr ring or rvlintlei- 2, surh for example as may he l'ouiid in eonnertion with the hub and axle of a rehirle like an automohile. or, ohviouslv. the parts may be reversed and the outer easing 1 may be stationary andthe 1nner easing 2 may revolve, there being he- Specification of Letters Patent.

Application filed January 21, 19l6. Serial No. 73.326.

tween these two erhndrieal easings or rings an annular spare ll whirh eontaiiis a series of eoinhined halls and rollers. Eaeh of, these ronibined deviees eonsists of a spheriral hall 4- a nd a hollow roller or sleeve 5. the hall sllying neatly and looselv within the roller 5 totlrhing the same lightlv at two points onl or praetieall floating therein so that it ran revolve freely. while the roller .3 whit-h ineloses the hall 4 lies siinila rlv with a loose revolving tout-h between the outer rrlinder and the inner evlinder 2. There is a series otthese halls and rollers in the annular spare I: eonsisting of as mam inenihers as desired. 'ithin the annular spare I; are also two rages ti eonsisting of annular strips of metal provided at intervals with rireular openings 7. having rurved inwanllypressed edges through the inside ofthe spheriot' whirh openings 7 portions eal surfaees ot' the halls 'lprojert into a position where said halls are elosely eontiguous and in revolving t'ontat't with the L shaped side wall l of the easing l and the similar opposite side wall :2" of the inner r vlindrieal musing :2. 'lt will he observed moreover that the outside of the eurved edges of the openings T in the rages ti form together rings between whirh the rollers 5 revolre in rlose [)l'UXlllllhV to the rings. as is rlearly shown in Fig. 2. These rages ti are spared apart and held in proper position by, means of a series of rivet H surrounded by tithes H. the tubes being lorated between the rages ti. while the rivets H pass through said nit-others ti and are headed at It) at both ends. 'lhese rirets alternate between the eoinhined hall and roller inenihers. as shown in Fig. l. and thus hold the parts in proper relation to eaell other. lnhrirating niedilnn IIHIYY he introdneed through the openings 11 at opposite sllltS of the hearing so as to luhrirate the spare between the halls. the rolleis, and the rages so thoroughly that all the t-ontaeting sin-fares will he ett'ertaally grea ed or oiled and will more open each other with the greatest possible ease and without ny wear and hy virture of the danhination ot the rollers with the balls hoth radial and lateral thrusts are provided for.

While in Fig. 2 I show a single series of the hall and roller members. in Fig. 3 I have dnplirated the same so as to make a stronger and heavier hearing to perform a larger work than is possible with a single series of balls and rollers in that it is possible therewith to take lateral thrusts in both directions; but the construction and arrangement of all the various parts of the ball and roller members, the inner and outer cylindrical casings, and the cages, are substantiall the same since the same results are attaine and, therefore, the practical accomplishment of the results is brought about through the same means with the same advantages increased and emphasized by the duplicate construction. In this case the outer rings 1 instead of being made L- shaped as before are made in one T-shaped )iece with a single, central inwardly projectmg flange 1 in lieu of the flanges 1.

7 Many changes in the precise structure and arrangement of the various parts may be made without exceeding the scope of the invention, and I therefore reserve the liberty of making all such changes as experience A flanges that engage the r01 may suggest to be wise and useful. I

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is z- 1 In a. ball and roller bearing, the combination of outer and inner rings having lateral annular flanges, a series of rollers in the Space between the rings, balls within the rollers, cages between the balls and rollers and the flanges, said cages having openings loosely engaged by the rollers, and spacing means for holding the cages firmly together at points intermediate of the rollers.

2. In a bearing, the combination of outer and inner rings having lateral annular flanges, between which rings is'an annular space, a series of rollers loosely placed in said space, a ball within each roller, and cages on the opposite sides of said balls and rollers and contiguous to the flanges, said cages having openings looselv engaged by the. balls, which openings have curved 3. In a ball bearing, the combination of inner; andouter casings having oppositelythe casings each comprising a hollow roller and a spherical ball within it, and cages on located flanges, a series of ball and roller members within the annular space between opposite sides of said members, the same being secured together at points intermediate of the members.

4. In a ball and roller bearing, the combination of a series of rollers having an opening therein, a loose spherical ball within each roller, and cages on the opposite sides of said balls and rollers, said cages having openings whose edges loosely engage the balls, and means for spacing the cages apart and holding them rigidly.

In a ball and roller bearing, the combination of an outer and inner ring between which is an annular space, a series of ball and roller members therein, each comprising a.hollow roller and a spherical ball within it, cages on opposite sides of said members formed of annular strips provided at intervals with circular openings that loosely engage the balls, and means for holding the cages in a rigid position relatively to each other.

(3. In a ball and roller bearing, the combination of inner and outer casings, a series of rollers in the space between them, balls within the rollers, and cages having circular openings loosely engaging the balls, said openings having curved edges.

7. In a ball and roller bearing, the combination of inner and outer casings, a series of rollers in the space between them, balls within the rollers, and cages having openings formed with curved edges which engage the balls. l

8. In a ball and roller bearing, the combination of inner and outer rings, a series of rollers in the space between them, balls within the rollers, and cages having openings whose edges are curved, and engage on their outside surfaces the aforesaid rollers.

9. In a hall and roller bearing, the combination of inner and outer rings, a series of rollers in the space between them, balls within the rollers. and cages having openings whose edges loosely engage the rollers and balls In testimony whereof I affix my signature.
